Gets the application-defined value associated with the specified list box item.
The index of the item.
Windows 95/Windows 98/Windows Millennium Edition (Windows Me) : The wParam parameter is limited to 16-bit values. This means list boxes cannot contain more than 32,767 items. Although the number of items is restricted, the total size in bytes of the items in a list box is limited only by available memory.
This parameter is not used.
The return value is the value associated with the item, or LB_ERR if an error occurs. If the item is in an owner-drawn list box and was created without the LBS_HASSTRINGS style, this value was in the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message that added the item to the list box. Otherwise, it is the value in the lParam of the LB_SETITEMDATA message.
